环境linux
git clone https://github.com/google/googletest

cd googletest
mkdir build
cd build

默认是生成静态库
执行cmake ../

编译make

生成动态库需要加参数
cmake -DBUILD_SHARED_LIBS=ON ../

新建个测试目录test
cd test
拷贝so与头文件
cp ~/googletest/googletest/build/*.so ./
cp ~/googletest/googletest/include/gtest/ ./ -a

生成测试源码main.cpp
#include "gtest/gtest.h"

int test(int a, int b)
{
    return a + b;
}

TEST(test, AddTest) {
    EXPECT_EQ(4, test(2, 2));
}

int main(int argc, char **argv) {
    ::testing::InitGoogleTest( &argc, argv );
    return RUN_ALL_TESTS();
}

编译
g++ -I ./ -L ./ -lgtest -lgtest_main -lpthread main.cpp

 ./a.out
